Abstract

Se proporciona un aparato de recepción que incluye la circuitería que está configurada para recibir una onda de radiodifusión que transfiere los datos digitales de acuerdo a una IP (Protocolo de Internet) teniendo una pila de protocolos de las capas en donde la circuitería esta además configurada para implementar un primer decodificador que usa una primer clave transferida en una primer señal de control en una primer capa para decodificar una segunda clave adquirida en una segunda señal de control transferida en una segunda capa, la segunda capa que es una capa más elevada que la primer capa en la pila de protocolos, y un segundo decodificador que usa la segunda clave decodificada para decodificar un componente codificado que configura un servicio de radiodifusión particular el cual es incluido en una flujo de datos obtenido a través de la onda de radiodifusión.
